The End of Our Sun #GreshamLecture Our nearest star, that is the engine sustaining life on Earth, will one day run out of fuel. When this happens, the Sun will start expanding dramatically, forming a red giant and engulfing much of the solar system including the inner planets, vaporizing oceans; formerly icy planets will become habitable.
